To aZZ whom it may concern:

Be it known that l, Janus ll ltoiuusin: a resident of the city ol Montreal, in the lhrovince of Quebec and Dominion of (mu ada, have invented certain new and useful Improvements in Dust and (lindcr Screens for Passenger-Coach l l indows; and l do hereby declare that the following is a tull clear, and exact (ilescriliition thereo't.

lr/ly invention relates particularly to screens for use on the outside ot passenger coaches to intercept sparks, cinders dust and the like for the purpose of enabling passcngers to keep the window open and have unobstructed view without being annoyed by cinders, etc.

The invention consists ot a pair of vertically arranged woven wire screens mounted on spring rollers disposed atv opposite sides oil' the windows means operated by the passenger for extending and returning the screens from the interior oi? the car.

For full compreheiision, however, of my invention reference must be had to the aceom aanying drawings forming a part of this specification in which similar reference characters indicate the same parts and wherein Figure 1. is an inside elevation oil. a. portion of a coach with the window casement broken away to show screen o uzrating means at one side oi the window; Fig. 2 a vertical sectional. view on l inc A .i't llig. 1 oi? the window casement and sash with the screen illustrated in dotted lines, extended; and F 3 is a horizontal sectional. view taken on line l3 B, Fig. 1.

lily invention consists of a. pair of vertically arranged woven wire screens 2 mounted on spring rollers disposed at opposite sides of the window in vertical boxes 3 having slits l through which one edge of the screen protrudes while this protruding edge has secured thereto a bar 53 mounted upon the outer end of an internally threaded sleeve 6 in telescopic relation with a screw 7 both sleeve and screw being mounted within the window casement and the inner end of the screw protruding into the car and having a handle or knob 9 thereon. The opening in the easement through which the screw protrudes is packed by a gasket 10 to prevent the entry of dust into the car. The boxes 3 have horizontal slits 15 in their outer walls at the lower ends to allow dust: entering through the slits i to dropout.

ll hen a passenger coach is traveling in the direction indicated in Fig. 3 and a pas senger wishes to open the window he should first turn the handle 9 at the :t'orward side of the window thus rotating the screw and causing the sleeve to more outwardly which has the eliect of causing bar 5 at the tor-ward side of the window relatively to the direc tion in which the train is traveling to be moved outwardly with relation to the window taking the screen at that side with it and extending such screen. as may be desired. \Vhen the knob or handle is turned in the reverse direction the bar will be drawn inwardly and the screen will. be returned to its box by the influence of the spring roller. The window may be raised at any time without moving either screen if desired.

l l hat I claim is as follows 1. The combination. with the car-side and movable. window sash of a. passenger coach. of a cinder guard within the space in the casen'icnt, the easement having a space therein and adapted to be moved to a position outside of the coach, and means within the coach and operatirely connected. to the guard for the purpose of moving the said guard.

2. The combination with the window casement and movable sash of a passenger coach. of a. pair of rolled cinder guards and means within the coach and operatively connected to the respective guards for the purpose oi. manually extending either of the said guards.

3. The combination with the window casement of a movable sash of a railway passenger coach, of a vertical spring roller mounted at one side of the winitlow, a wire screen wound upon the roller and adapted to be extended laterally with relation to the window, means within the coach, means offecting an operative connection between the means within the coach and the screen for the pitlrpose of manually extending the screen.

a. The combination with the window casement of a movable sash of a railway passenger coach of a vertical spring roller mounted at one side of the window, a woven wire screen mounted upon the roller and adapted to be extended laterally with relation to the window, manually operated means carried by the window casement, telescopic means efiecting an operative connection between the manually operated means upon the window casement and the screen.

5. The combination with the window casement of a movable sash of a railway passenger coach, of a pair of vertical spring rollers mounted at opposite sides of the window, woven wire screens mounted upon the rollers and adapted to be extended laterally with relation to the window, manually operated means carried by the window casement, a pair of screws mounted in the casement, a pair of internally threaded sleeves in telescopic relation with the screws and secured at their outer ends to the screens for effecting an operative connection between the manually operated means upon the win dow casementand the screens, and means for guiding the sleeves.

6. The combination with the window casement of a movable sash of a railway passenger coach, of a pair of boxes located at opposite sides of the easement and having vertical slits near one side and horizontal slits near the lower ends, a pair of vertical spring rollers within the boxes, woven wire screens wound upon the rollers and pro truding through the vertical slits, bars carried by the protruding ends of the screens, a pair of screws mounted in the casement, internally threaded sleeves in telescopic relation with the screws and secured to the bars, braces from the sleeves to the bars and ham dles mounted upon the inner ends of the screws, the said inner ends of the screws protruding inwardly through the easement and having the handles located within the coach.

In testimony whereof I have signed my name to this specification in the presence of two witnesses JAMES MORRISON.
